no, just commute to blynk server , not custom
original setting at blynk server not custom…mybe i need to uninstall and re install back this app…
are you sure to have wifi enable ?
yes…i always use this app…only today can’t huhuhu…i try install at android phone = OK
I just connected to blynk server,
work well for me
after uninstall and reinstall back all ok…thanks friend
hi friends…what function timer.run() ? is’t function like delay?
i try use Virtual Led for my project (other project) i use blynk timer and result is = led blinking not solid.
void sensor()
{
sensora = digitalRead(sen1); // read IR sensor
if (sensora == HIGH){
ledv1.on();
}
sensorb = digitalRead(sen2); // read IR sensor
if (sensorb == HIGH) {
ledv2.on();
}
sensorc = digitalRead(sen3); // read IR sensor
if (sensorc == HIGH){
ledv3.on();
}
sensord = digitalRead(sen4); // read IR sensor
if (sensord == HIGH) {
ledv4.on();
}
else {
ledv1.off();
ledv2.off();
ledv3.off();
ledv4.off();
}
}

void setup()
timer.setInterval(1000L, sensor);This is what makes the Timer work. Without it, your timers will not execute.
This command creates a timer that executes the function sensor() every 1 second.
You may find this link useful, as the timer has many capabilities.
Simple Timer (Blynk Timer)
so if i need turn ON led when sensor get input what should i do? so blur right now hahaha.
if i use blynk timer LED blink not solid ON
That is what your code does. Every 1 second it checks the state of the digital pins and turns the corresponding LED on or off as the If statement tells it to.
What exactly is it that you are trying to accomplish?
else {
ledv1.off();
ledv2.off();
ledv3.off();
ledv4.off();
ahah, you have grouped else !!!
try this
sensora = digitalRead(sen1); // read IR sensor
if (sensora == HIGH){
ledv1.on();
} else {
ledv1.off();
}

waaa…good idea hahaha…ok i test now
toro_blanco… i try to control my lamp and fan using blynk…it aslo have 2 way control, that mean i can on/off using blynk and also can on/off using wall switch…
so i need virtual Led to show status my lamp or fan…
Alexis_Cabrera it’s work…thanks friend…
you are welcome
hi friend @ Alexis_Cabrera …are u familiar with terminal widget function ?
Just look up the terminal widget example. Well documented. You’ve two choices writing to terminal. Use terminal.print or blynk.virtualWrite to the virtual pin. Recommend the second mode.
i already try terminal widget example and it work with i2c lcd display…now i try use RGBmatrixPanel with arduino mega…without Blynk all ok, coding function as well…
after add terminal widget = not work…
here my coding with terminal widget function…almost 1 week i working on it but still not work hahaha…

Closing this topic as it is solved.
